This was what Wayne had posted that I tried:
Just for kicks and giggles here's a list of all the files you need for the install. acfpdf.txt acfpdfu.dll acfpdfuamd64.dll acfpdfui.dll acfpdfuiamd64.dll acXMLParser.dll amyuni.inf cdintf.dll PDFInstall.exe xmllite.dll All the files come from \MAS\HOME directory except for xmllite.dll, which you can grab from any Win7 workstation, just do a file search for it. I've only tested it in a few situations but it seemed to work everytime. It's probably not by the book by any means but it does work. Also, I always find it useful to disable UAC, then run the pdfinstall.exe as administrator. Since I've done it this way I haven't had to rename the printer.
